Bro just go pick up heavy an gally the well, or vortex with weaking/arc nade with jolt an witherhord his will make anyone leave the well or die.
If you cant destroy the well find a way to make em abandon the well.
Edit: if you wanna just punch em solar titan shoulder charger still yeets mfs far as hell, yeet em out there own well an shotgun. You have way to many options, and then super if I play titan an see a well more then likely ima thunder an clear that whole spot out
